6 Claims.

My invention relates to improvements in archery bows and has particularreference to a sight device to be mounted upon the bow.

An important object of the invention is to provide a sight device whichis rigidly secured to the bow so that it will not be thrown out ofalignment due to the whip of the bow when shooting.

A further object of the invention is to provide means whereby the sightis adjustable vertically and horizontally in straight lines.

A further object of the invention is to provide a sight device of theabove-mentioned character having vertically horizontally adjustableparts which are clamped in the selected adjusted positions by a singleelement.

A further object of the invention is to'provide a flat plate which isclamped to the bow with its surface next to the bow provided with agroove or recess to receive the head of the clamping screw which isthereby retained out of contact with the adjacent surface of the bowwhen the plate is applied to the bow.

A further object of the invention is to provide a device of theabove-mentioned character having a slide which is vertically adjustablelongitudinally of the attaching plate and a second slide which ishorizontally adjustable with .respect to the first slide. I

Other objects and advantages of the invention will be apparent duringthe course of the following description.

In the accompanying drawing forming a part of this application and inwhich like numerals are employed to designate like parts throughout thesame,

Figure 1 is a left side elevation of an archery bow showing my sightdevice applied thereto,

Figure 2 is a similar view, upon an enlarged scale, parts broken away,

' Figure 3 is a rear end elevation of the sight device,

invention, the numeral l0 designates an archery bow having an enlargedintermediate portion forming a handle ll. Secured to the ends of the bowI0 is a string l2 engaging an arrow l3, to project the same.

My sight device comprises an attaching plate l4, formed of metal or thelike. This attaching plate is elongated and is preferably flat. Theattaching plate is provided with a longitudinal slot I5 extendingthroughout the major portion of the length of the same and terminatingshort of the ends of the plate. The rear face of the attaching plate ismilled out to provide a longitudinal groove or recess IS, incommunication with the longitudinal slot l5 and the groove or recess l6extends beyond the ends of the slot [5 and terminates short of the endsof the attaching plate. The front face of the plate 14 is also milledout to provide a longitudinal groove or recess 11, in communication withthe slot l5 and extending beyond the ends of this slot and terminatingshort of the ends of the plate I4. The grooves l6 and ll form a webbetween them, having the slot l5 therein.

Means are provided to rigidly secure the attaching plate l4 to the bow10, comprising U- shaped straps l8 and H! which are adjustably securedto the longitudinal edges of the plate l4, adjacent to its opposite endsand outwardly of the recesses I6 and l I by screws 20 or the like. Theplate I4 is arranged upon the front face of the bow l 0 and contactstherewith and the groove or recess I1 is next to this front face and theU- shaped straps l8 and receive the bow therein. By manipulation of thescrews 20, the straps l8 and I 9 and the attaching plate l4 are rigidlysecured to the how. The attaching plate 14 is also provided adjacent toits ends and outwardly of the grooves or recesses I6 and I! withscrewthreaded openings M to receive pointed set screws 22, which may beadjusted so that their pointed ends will be forced slightly into thefront face of the bow. These set screws and straps rigidly secure theattaching plate l4 to the bow so that the attaching plate cannot bedisplaced by the whipping action of the bow when shooting.

Arranged upon the front face of the attaching plate I4 is a T-shapedrear slide 23 including a vertical head 24 and a horizontal arm 25. Thehead 24 is provided upon its rear face with a vertical tongue 26,Figures 3 and 6, which is slidably mounted in the groove or recess H.The horizontal arm is provided upon its front face with a horizontallongitudinal groove or recess 21. The head 24 is provided with atransverse opening 28, Figures 4 and 6. The rear slide 23 is mountedupon the attaching plate 14 to be adjusted longitudinally thereof in astraight line.

Disposed forwardly of the rear slide 23 is a front slide 29, mountedwithin the groove of the recess 21 and the slide 29 has a longitudinalslot 30. The numeral 3i designates a clamping screw, passing through theopening 28, slot 30 and the slot and this clamping screw carries amilled nut 32 and a washer 33 preferably arranged beneath this nut. Theclamping screw has a flat head 34, which is "mounted within the grooveor recess l6 and spaced from the face of the how. The slide 29 isadjustable horizontally of the arm 24 in a straight line, and the singleclamping screw I3 is manipulated to permit of the vertical andhorizontal adjustment of the two slides and to clamp them inthe-selected positions,

Rigidly secured to the free end of the slide 29 is a horizontal arm 35,disposed at a right angle thereto. This arm carries at its front end asplit ring 36, having ends 31 which may be drawn together by a screw 38.The split ring is provided with an inwardly projecting lug 36'. At itsrear end, the arm 35 carries a continuous ring 39, having radialscrew-threaded openings 40, to receive adjustable centering screws 4|.

A tube sight is provided, including a tubular body portion'42, adapted.for insertion within the split ring 36 and the ring 39. The tubular bodyportion isgpr'ovided witha transverse slot or recess .42, to. receivethelug 38., whereby the tubular body portion 42 is positively heldagainst relative longitudinal movementfldue to the whip action of thebow. J The screws 4| are adjustable to adjust or center the tubular bodyportion 42 which may be clamped within the split ring 36. Disposed atthefront end of the tubular body portion 42 is a ring 43 ,carryinga pin44 provided with a bead 45." The ring 43 is clamped to the front end ofthe tubular body portion 42 by a ring-cap 46, having screw-threadedengagement with the end of the tubular body portion 42. At the rear ofthe tubular body portion 42 is a disk 41 which is clamped to the tubularbody portion 42 by a ring-cap 48 having screw-threaded engagement withthe tubular body portion and the disk 41 has a sight opening 49, asshown.

As shown in the drawing, the arm 35 and tube sight are disposed upon theleft side of the bow I0, although they may be disposed upon the rightside, which can be readily effected by inverting the attaching plate l4and parts carried thereby.

With the parts assembled as shown in the drawing, the adjustment of thetube sight with respect to the arm 35 is effected by manipulation of thesplit ring 36 and screws 4| and the tube sight is clamped in theselected adjusted position with respect to the arm 35. By loosening thenut 32 the two slides 23 and 29 may be adjusted vertically as a unit,while the slide 29 may be adjusted horizontally with respect to theslide 23. By tightening up the nut 32 the two slides 29 and 23 areclamped together and the rear slide 23 is clamped to the attaching plateH. The screw 3| is therefore common to both slides. Since the head 34 ofthe screw works within the groove or recess [6 this head is out ofcontact with the adjacent face of the bow and hence there is no bindingaction between the head and the bow to prevent the vertical adjustmentof the slide 23. The attaching plate l4 being fiat and not arched, thesame may be securely clamped to the how so that it will not be displaceddue to the whipping action of the how when shooting. The tubular sightcan be adjusted with respect to the bow to meet sighting requirements ofthe archer under the conditions of use with respect to the target,windage, etc. The adjustment of the tube sight is effected in straightlines both vertically and o a y- It is to be understood that the form ofmy invention herewith shown and described is to be taken as a preferredexample of the same and that various changes in the shape, size, andarrangement of parts may be resorted to without departing from thespirit of my invention or the scope of the subloined claims.
